He writes about the power of social scoring in his new boo,k "Return on Influence: The Revolutionary Power of Klout, Social Scoring, and Influence Marketing."

"We are really in the middle of a business and communication revolution," Schaefer said on "CBS This Morning." "Now that we have high-speed Internet and free, easy-to-use publishing tools like blogging and Facebook and Twitter, everybody can publish. Everybody can have influence.

"And companies now ... are trying to measure that. They're trying to quantify how well people can create buzz. And as you can imagine, a lot of big companies and brands want to be all over this. They want to find powerful word of mouth influencers and reward them and give them stuff. I mean, lots of great stuff like trips and gaming systems."

In addition to free stuff, people who weigh in on products or services also get notoriety from their reviews.

"You're being rewarded for your influence," Schaefer said. "Who's to say the world expert in Porsche cars isn't an 18-year-old person in Owensboro, Kentucky? Now that can be known. Now you can have visibility and be rewarded. It's a very exciting time."
